RBO Grinding Room Build (12'x6.25') - Looking For Advice

[Linus Knives]

I've installed 2 so far... will be installing a third in my gym. As far as advice goes I'd air on the larger side, the cost variance isn't high and you'd rather it work less than being on full tilt all the time.

Thanks. My area is pretty small so I should be fine with 12,000 but I'll look into it for sure.
BTW: I love your videos on YouTube!

I'd frame a 24X30 window to the right of the door, and an 18X30 window on the end wall over the benches. More shop visibility, fewer surprises.

Don't forget to put in a ceiling socket to plug the hanging air filter into.

So I think what I'm going to do in the short term is use some thick gauge plastic tacked up on the frame. This will help me learn the space a little and use it. Will also allow a ton of light in.

On the back wall I'm going to use some corrugated tin as a wall spark guard.

Heck yeah on the ceiling socket, forgot about that.

I did get some triple T8 - 4ft - 5000K lights installed!

While 8-12mil plastic sheeting will work, it may build static and get coated with grinding dust. At least that is what I have heard. If you go with a plastic wall, I would still half wall the bottom 4-feet in plywood, paneling, or drywall.

I see you went the easy route when putting in the cross braces, and raised every other brace. If you half wall it for now, here is how to make those up-down braces even ...sister a second 2X4 on the top of each lower one to make the all the same height.

From what my AC people told me (and what I read) too large can be worse than too small. Too large will cycle more frequently, but may not run long enough to lower the humidity. Short cycling is not good for AC compressors.

SharpBits, J. Keeton is also in TX. Our AC's don't generally cycle short periods. What you state is 100% true, however, I've never known anyone who had this problem. I have known many who have experienced the opposite problem.

 

[J. Keeton]

Haven't gotten much done lately... but I cut the bottom plate and rolled some grinders in for scale...



I think I'll be putting up some plywood partial board sheeting inside and out on this wall. Still debating a window on the right hand side of the door... not sure about that.... I like the idea of having extra wall storage behind benches (peg bords, shelves, etc) and the window could get in the way...

 

[Linus Knives]

Nice! I'm contemplating building myself a grinding room as well...
Working on a bunch of other stuff but I think it's coming next!

If I had it to do over, my grinding room would be lined in milkhouse board, and I would plan the ventilation system with a reputable HVAC contractor.

it's true- my enclosure is plastic and dust does like sticking to it. I have a spray bottle with dish soap and water and spritz it down every now and then. It's not an ideal situation, I'm going to make some changes soon and they will likely involve drywall and dimensional lumber instead of tarp and shower rings

That milkhouse board looks pretty nice!

Looks like OBS will be the cheapest option on the walls... The 7/16hs sheeting is cheaper than drywall is now days. I'm calculating about $450 worth of sheathing for these 2 walls.

You know... I've been thinking about this... With the room seeing a good deal of sparks on the regular, it may be best to just drywall it over OBS. In addition to a 'spark plate' around the inside perimeter where the grinders will be. Do yall think that's a valid concern with the OBS?

I guess I could also go OBS and then put up a liner that's grinder height all the way around with corrugated tin or concrete board as the 'spark plate'... drywall is such a pain...

 

[Stacy E. Apelt - Bladesmith]

I did not like the OBS choice, but didn't post it. I would just drywall. A thin aluminum or steel spark guard where the sparks fly is very wise.

 

[J. Keeton]

Well... sorry Stacy E. Apelt - Bladesmith ; I ended up going with the OBS.



I'm thinking of putting up this cut corrugated tin I have across the drywall in the green section here and maybe buy some cement backing board for the red section.

On the cement backing board (hardi board) I was thinking of going from the ground to about 6' with added stud supports at the top so that nothing can fall into the cavity behind the hardi board.

 

[Stacy E. Apelt - Bladesmith]

That is an excellent idea.

 

[J. Keeton]

Decided the cement board would be cleaner than the Tin... Making progress! Also put exterior covers on the outlets.





This last one shows the 'blocking top caps'
